Eucalyptus Lemon Essential Oil, steam-distilled from the leaves of the Eucalyptus citriodora tree, is known for its fresh, citrusy, and slightly sweet aroma, attributed to its high citronellal content. This tall evergreen tree, native to Australia, boasts smooth dimpled bark, showcasing shades of grey, cream, and pink. Despite its Australian origins, Eucalyptus Lemon Oil is primarily cultivated in Brazil and China.
